Thus, there is a risk of the sheath swelling excessively, the connection points opening, or the sheath being damaged. 25 is reduced. The system uses a pressure sensor, electronic pressure measurement, temperature sensor, or separate There is no electronic control unit. Air temperature is determined by the external device's own settings. The selected settings are 32°C, 38°C, and 43°C, which are only example application values. This structure... By reducing temperature differences and moisture accumulation in the proximal optical junction area, it prevents fogging. It helps to prevent or reduce [the effects of the virus]. 30 The main purpose of the invention is to separate the camera body from the optic at the distal end of the endoscopic optic. the proximal optical connector where the component joins and remains within the interior volume of the sterile camera case.

Sterile camera case (5) 15 with a separate temperature sensor, temperature sensing element or temperature control mechanism It is not available. Heated air supplied from the external hot air heater device (1) through the air transmission hose (2) The air is transmitted through the air inlet port (9) and into the internal volume of the sterile camera sheath (5). also includes an air duct, routing line, distribution structure or separate circulation path It is not present. The heated air diffuses freely within the enclosed inner volume of the sheath and mixes with the existing air. 20 When the internal pressure increases by introducing air into the sheath, the mechanical pressure-controlled relief valve (3), It opens at its mechanical opening threshold, allowing excess air to escape from the sheath. Internal pressure When the pressure decreases, the valve can return to the closed position. This prevents the sheath from over-inflating and disrupts the connection. This reduces the risk of the compartments opening or the casing being damaged. Mechanical pressure controlled relief valve (3), 25 without requiring sensor or electronic measurement It is a mechanically operated output element.

The proximal optical junction where the camera body (6) and the optical component (7) are joined, This is the key area where fogging needs to be reduced. This area is where the endoscopic optic is inserted into the patient. It differs from the proximal end. The heated air supplied to the sheath's internal volume differs from the proximal 5 in question. its free spread around the connection area reduces temperature difference and moisture accumulation. It helps reduce or prevent fogging. The barrier integrity between the sterile outer surface and the non-sterile inner volume of the sheath is maintained. During the process, it is not necessary for the air supplied into the case to be sterile. Sterile camera case (5), air inlet port (9), mechanical pressure controlled relief valve (3), optical inlet port (10) and related 10 Fasteners can be manufactured as a sterile, single-use, one-piece product.
